One of the most plaintive images to come out of the Syrian region recently is making the rounds of the internet – that of a 4-year-old boy found wandering alone in the Jordanian desert, separated from his family.

Marwan happened across United Nations aid workers, one of whom leaned over, seemingly to ask why he was all alone.

Andrew Harper, the United Nations Refugee Agency’s coordinator in Jordan, shot the photo and posted it on Twitter.

In other Syria news this week, Secretary of State John Kerry criticized Russia's role in the escalating violence, according to a report by Michael R. Gordon, David E. Sanger and Eric Schmitt of The New York Times. President Obama and other Western leaders have dropped objections to proposals by Saudi Arabia and other countries to supply vetted rebels groups with portable antiaircraft weapons called "manpads," administration officials say.

Saudi Arabia, frustrated by the failed talks, has offered to supply rebels with anti-aircraft missiles, The Wall Street Journal reports. The Journal says rebel sources claim the U.S. government is paying their salaries to fight Assad forces. The Southern Front brigades allegedly received $3 million in cash in salaries during two meetings in Jordan. Congressional aides told the Journal about scheduled meetings next week with Syrian opposition leaders, who will allegedly seek extra arms to battle al-Qaeda and al-Nusra factions.

CNN made it into Addana, Syria, a town held until recently by one of these factions, the Islamic State in Iraq and Syria. ISIS imposed an Islamic state and carried out executions, according to rebels who kicked them out.

The BBC's Lyse Doucet got exclusive access to a center in Homs, where men evacuated from the Syrian city are being held. Around 300 men are being held for questioning in Syria after they left the rebel held area of Homs during an evacuation involving the UN last week.
